Strap tightener

Abstract

A strap tightener is disclosed. The tightener includes a base member having edges for guiding a pair of threaded members. A drive member is mounted between the threaded members and a keeper is located adjacent the base for maintaining the base generally parallel to the length of strap during tightening.

What I claim is: 
     
       1. A strap tightener for tightening a length of strap intermediate its ends comprising, in combination, a longitudinally extending base member, opposed guide walls defined on opposed sides of said base member, two longitudinally extending threaded members positioned adjacent said guide walls, said guide walls receiving and guiding said threaded member, a drive member connected to and extending between said threaded members, and a keeper means adjacent said base member and positioned immovably relative to said base member for maintaining said base member generally parallel to the length of strap, said keeper means comprising a keeper bar extending between said longitudinally extending threaded members, said keeper bar defining opposed openings for receiving said threaded members, said base member and said keeper bar defining a recess for receiving such strap, said drive member being moved along said base to tighten such strap. 
     
     
       2. A strap tightener, according to claim 1, wherein said drive member is integrally connected to said threaded members and extends between said threaded members. 
     
     
       3. A strap tightener, according to claim 1, wherein said drive member defines spaced threaded holes, said spaced threaded holes receiving respective ones of said longitudinally extending threaded members. 
     
     
       4. A strap tightener according to claim 3, wherein said longitudinally extending threaded members include heads at one end, said heads engaging said keeper means. 
     
     
       5. A strap tightener according to claim 1 including nut members threadedly mounted on said longitudinally extending threaded members adjacent said keeper bar. 
     
     
       6. A strap tightener for tightening a length of strap intermediate its ends comprising, in combination, a base member having a flat base and upstanding curved sidewalls, a pair of opposed longitudinally extending threaded members adjacent to and received by said curved sidewalls, said flat base of said base member defining a recess at one end, a keeper bar positioned immovably relative to said base member adjacent said recess and defining opposed openings for receiving said threaded members, said recess of said flat base and said keeper bar defining a passageway for such strap and a drive member having opposed threaded holes for receiving said longitudinally extending threaded member whereby rotation of said threaded members moves said drive member to tighten such strap. 
     
     
       7. A strap tightener for tightening a length of strap intermediate its ends comprising, in combination, a base member having a flat base and upstanding curved sidewalls, a "U" shaped member having threaded legs positioned adjacent said upstanding sidewall and an integral drive member connected to said threaded legs, said curved sidewalls receiving and guiding said threaded legs, a keeper bar having opposed openings for receiving said threaded legs positioned immovably relative to said base member, said flat base of said base member defining a recess at one end, said recess of said flat base and said keeper bar defining a passageway for such strap and a pair of nuts mounted on said threaded legs adjacent said keeper bar, whereby rotation of said pair of nuts moves said "U" shaped member to tighten such strap.
